Emulator

I don't have an audio dump since the emulator's audio dump didn't have any sound bugs so I didn't bother to upload it, but here's a video of what actually happens in-game.

It seems like it might be performance issues, but I don't know why that would happen since this is the only game I'm not capable of running perfectly.

Is it not an issue with the emulator in itself that the game can't be ran, though? It seems strange that this is the only game out of a dozen or so that I've tried (even the latest ones like Skyward Sword run perfectly) that does this, even though it's the only game that I've ever had to turn down things like AF or the resolution for. Are there any settings specific to this game that need to be tweaked that the wiki page for it doesn't have listed?

It's also probably worth noting that I just downloaded the old Dolphin 3.0 build, and it runs the scene perfectly smoothly even at a high resolution, with the only issue being that the wii remote loses sync a little while after the scene during the interview.

No, it's not worth noting, your computer is slow and we can't do
anything/don't care about it.

Are there any members of the project without sticks up their asses that could maybe take a look at it?

I don't think it's possible to find anyone important without a stick up their ass around here, we get enough complaints about performance without people inadvertently filing issues about them. v_v;

Just overclock to fix this. Yes, I'm serious, Dolphin is a thing that even people with 3570Ks need to overclock for. IIRC, MaJoR has his at 4.7 GHz and still runs into perf issues once in a blue moon.

But is it really performance issues if the game works perfectly fine in a different build with the exact same settings? I mean, I'm no developer, but that seems like common sense.

Not really. For emulators (well, once they're past the early stages of development), performance tends to get worse as development goes on and things are emulated more and more accurately. And 3.0's goddamn ancient, so naturally it's gonna run much faster (and also a ton of stuff's gonna be broken).

Generally the devs (well, aside from neobrain) DO care about performance issues, but it's not the primary goal. They try to optimize where they can (e.g. fixing up DSP HLE so people don't always have to use LLE for perfect audio, making perfqueries optional, fixing noticeable performance regressions from shader-uids-awesome), but there's not much can be done with all this bug-fixing and accuracy leaking in.

Oh, I see. Thanks!
